iam in leafy spring adventure and iam stuck at last level 28 fighting the boss for 2 days now, whats killing me is all enemies at level 5 and 3 bosses behind each other, iam level 27, damn it cant find the right formation

Use Wolf Riders backed with shaman instead of archers and archangels, you do not need that much magic/piercing damage this fight. The wolves have light armor, so all those archers are useless firing at them.

I just can't believe you get stuck on this, your hero realy rox !I don't understand why doin adventure mode if you already have better stuff than what u can get there. One tip is upgrade ur units !! and use ur brain for formations, not only ur overstuffed hero.

In the formation or my overall units? lol. The ones in the formation take out the wolves fast enough that they don't get a chance to run over your formation. I always have a lot of mages stocked up since they are the main part of all my formations.
